Modelo de eliminación de desperdicios basado en Lean Manufacturing y Lean Maintenance para el incremento de la eficiencia en la industria  manufacturera / Waste Reduction Model based on Lean Manufacturing and Lean Maintenance for increasing efficiency in the manufacturing industry

Aucasime Gonzales, Paola Priscilla, Tremolada Cruz, Sofia Fernanda 15 January 2020 (has links)
En el presente artículo se aborda la problemática de la baja eficiencia de un proceso productivo en una empresa manufacturera. Esta investigación busca integrar y modelar diferentes herramientas de la ingeniería, con un modelo más eficiente que evite costos altos de mantenimiento de los equipos de producción, sin incurrir en elevados costos por implementación. En tal sentido, este artículo presenta un Modelo de Reducción de Desperdicios que busca reducir el tiempo de set up y desarrollar una gestión del mantenimiento adecuada para lograr el incremento de la Eficiencia General de los Equipos (OEE). La validación del modelo ha sido realizada en una empresa de manufactura de neumáticos en el Perú y arrojó resultados positivos tales como un incremento del OEE de 13%, una reducción de tiempos de set up de 22.5% y como consecuencia un incremento en la capacidad de cambios de componentes, la externalización de 37 actividades y un incremento del 80% en el índice de conocimiento de los operarios involucrados en la propuesta. / This article addresses the problem of low efficiency of a production process in a manufacturing company. This research seeks to integrate and model different engineering tools, with a more efficient model that avoids high maintenance costs of production equipment, without incurring high costs for implementation. In this regard, this article presents a Waste Reduction Model that seeks to reduce set-up time and develop proper maintenance management to achieve the increase in General Equipment Efficiency (OEE). The validation of the model has been carried out in a tire manufacturing company in Peru and yielded positive results such as an OEE increase of 13%, a set-up time reduction of 22.5% and as a consequence an increase in the capacity of component changes, the transformation of 37 activities from internal to external and an 80% increase in the knowledge index of the operators involved in the proposal. / Tesis

Implementación de la metodología Lean Maintenance para la línea de producción “gres porcelánico” en una empresa del rubro cerámico

Velezmoro Jáuregui, Mark Alexander, Solís Tinoco, Alonso Edwin 10 June 2019 (has links)
Esta investigación aborda la mejora en la línea de producción de gres porcelánico en una empresa de cerámicos utilizando las herramientas de Lean Maintenance. En el primer capítulo, se muestra un marco teórico que permite conocer los orígenes de la metodología a empleada en este trabajo. En el segundo capítulo, se hace mención de la situación actual de la empresa y el problema principal que está asociado a las horas de intervención por mantenimiento no programado. En el tercer capítulo, se selecciona la metodología y las herramientas del Lean Maintenance para su implementación, los cuales registraron mejoras en la estandarización de los procedimientos operativos (SOP) en 33%, reducción del 20% en la secuencia de tareas y mejora en la reposición de inventario estándar en 42%. Por parte de la implementación del Mantenimiento Productivo Total (TPM) se pudo reducir los tiempos de limpieza e identificación de los equipos en 40% y 60% respectivamente, y por último se finaliza con la implementación del Mantenimiento Basado en la Confiabilidad (RCM) que permite aumentar el tiempo medio entre fallas (MTBF) en 25.81% y reducir el tiempo medio de reparación (MTTR) en 54%. Como resultados finales se logró un incremento de la disponibilidad en 13.26%, esto significa un aumento en la producción de 8,618 metros cuadrado al año. En el cuarto capítulo, se muestra la viabilidad técnica y económica del proyecto. Finalmente, se presentan las conclusiones y recomendaciones para su sostenimiento en la empresa. / This research addresses the improvement in the production line of porcelain stoneware in a ceramic company using the tools of Lean Maintenance. In the first chapter, a theoretical framework is shown that allows knowing the origins of the methodology used in this work. In the second chapter, mention is made of the current situation of the company and the main problem that is associated with the hours of intervention for unscheduled maintenance. In the third chapter, the methodology and the tools of the Lean Maintenance for its implementation are selected, which registered improvements in the standardization of the operative procedures (SOP) in 33%, reduction of 20% in the sequence of tasks and improvement in the replenishment of standard inventory at 42%. On the part of the implementation of the Total Productive Maintenance (TPM) it was possible to reduce the cleaning and identification times of the equipment by 40% and 60% respectively, and finally it ends with the implementation of Reliability Based Maintenance (RCM) that allows to increase the mean time between failures (MTBF) by 25.81% and reduce the average repair time (MTTR) by 54%. As final results an increase of the availability in 13.26% was achieved, this means an increase in the production of 8.618 square meters per year. In the fourth chapter, the technical and economic feasibility of the project is shown. Finally, the conclusions and recommendations for its sustainability in the company are presented. / Trabajo de investigaciòn

LEAN maintenance model based on change management allowing the reduction of delays in the production line of textile SMEs in Peru

Arrascue-Hernandez, G., Cabrera-Brusil, J., Chavez-Soriano, P., Raymundo-Ibañez, C., Perez, M. 06 April 2020 (has links)
This article examines the problem of production line delays in a textile small- and medium-sized enterprise (SME) that produces polyester fibre from recycled bottles, based on orders. Factors that have resulted in production line delays include prolonged unscheduled maintenance time, and preparations and adjustments prior to operating the equipment. To address the problem, a model was developed applying lean manufacturing tools through change management, with the aim of increasing equipment availability and useful life. To validate the model, a pilot was developed to determine how the increase in equipment availability helps reduce delays in the production line, which eventually improves completion of customer orders.

Applying lean maintenance to optimize manufacturing processes in the supply Chain: A Peruvian print company case

Ramos, Edgar, Mesia, Ron, Alva, César, Miyashiro, Rudy 01 January 2020 (has links)
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado. / This research analyzes the Peruvian organic production coffee industry, the relationship between Supply Chain Management (SCM) and Supply Chain Integration (SCI) concerning the performance of the Cooperatives and the Coffee Associations in Junin Region of Peru. It also analyzes the current scenario of the Coffee Sector and the participation of the Supply Chain (SC) in the processing and distribution of Organic Coffee in Junin, Peru. A diagnosis was made to the certified organizations from the market. The diagnosis and the surveys indicated that they do not have a correct flow of information, shared goals and objectives, strategic decisions, and sourcing materials among the different parties demonstrating the lack of interrelationship among the members. The final objective of this research is to improve the competitiveness of these organizations through the increase in the performance of the SC, for which a model of supply chain integration is proposed. / Revisión por pares
